NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary

Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35

Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…

TOI-2374 b and TOI-3071 b: two metal-rich sub-Saturns well within the Neptunian desert

Alejandro Hacker, Rodrigo F. Díaz, David J. Armstrong +40

We report the discovery of two transiting planets detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V and an F8V star, respectiv…

The XUV-driven escape of the planets around TOI-431 & Lupi

George W. King, Lía R. Corrales, Jorge Fernández Fernández +4

One of the leading mechanisms invoked to explain the existence of the radius valley is atmospheric mass loss driven by X-ray and extreme-ultraviolet irradiation, with this process…
